The dynamics of the one-dimensional transverse Ising mode is studied by means of Mori's continued-fraction representation in the three- and four-pole approximations. The required moments are obtained using the longitudinal time-dependent correlation function calculated in the c-cyclic approximation and various cut-offs of the continued-fraction representation are analysed.
